Twinned Montana Sapphire crystal,
Eldorado Bar, Helena MT.
5.05 cts, 9.96 mm x 7.12 mm x 5.87 mm

Here is a unique twinned Montana Sapphire from the Missouri River Alluvial deposits. Twinned sapphire crystals from these deposits are rare.

Although it may not be easy to see in the photos, this twinned sapphire crystals is green down one axis and blue down the other. The crystal has some micro inclusions, would be interested to know what they are, but I need stronger magnification for that. 

Another very odd feature is the surface texture of this alluvial sapphire, I have not seen such odd surface feature from this deposit.
